A portable HEPA filter chamber is provided with a pair of wheels and a handle whereby it can be moved by a person in the manner of a two-wheeled hand-truck. One or more inlet openings receive air from an area to be cleaned, dried, or decontaminated. An air outlet is adaptable to the air inlet height of standard, widely-used carpet dryer blowers. Pre-filters are provided in the portable chamber upstream of the HEPA filter. Strapping holds the blower unit to the outlet of the filter chamber. Support wheels and a handle enable convenient hand-truck type operation to facilitate movement of the combination when and as needed in the area being dried. An upstanding perimeter flange, and the handle, when retracted, serve as a fence to stabilize multiple chambers, when stacked for storage or transportation in a truck. The exterior wall of the chamber is shaped for inter-fitting with others to minimize floor space for storage and transporting. Hook-on adjustable air flow inlet valves are usable for mold remediation operations.
